Field Testing of Major Trenchless Technology Methods for Road Crossings
Ground displacements and borehole stability are always of prime concern during trenchless technology installations under pavements, and in close proximity to existing buried utilities and structures. Stable boreholes also relate to successful completion of the projects. The Missouri Department of Transportation (MoDOT), University of Missouri — Columbia, Michigan State University, and several industry participants have joined forces to conduct a research program to evaluate borehole stability. The objective of this research is to study the ground movements caused by pipe jacking, auger and guided boring and horizontal directional drilling methods. The soil displacement in the vicinity of the cutterhead, reamer and at the ground surface will be examined. To conduct the research, several field installations were conducted at the University of Missouri's Capsule Pipeline Research Center during the summer of 2002. In addition, an actual road crossing with pipe jacking method was closely monitored. The results of these unique field evaluations will be incorporated in the MoDOT specifications and guidelines and a summary will be presented in this paper. This will bring cost saving information for future MoDOT projects.
